DRIVING-GEAR FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 662,015, dated November 20, 1900.

Original application filed March 8, 1899, Serial No. 708,191. Divided and this application filed HHB 18, 1900. Serial N0! To (tZZ whom it may concern.-

Be it known that I, LA VERNE W. NoYEs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Driving-Gear for Windmills, of which the following isa full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification. t

My invention relates to a driving-gear particularly designed for windmills, my object being to provide a structure whereby a plurality of reciprocating parts, as pump-rods, may be actuated by a single power device, as the wind-wheel.

While I have illustrated my invention as particularly applicable to a windmill, it will be understood that the invention is equally applicable to other mechanisms.

The present application is a division of an application filed by me March 8, 1899, Serial No. 708,191. In said application I have illustrated the driving-gear herein claimed as associated with a form of swiveling device whereby three reciprocating pump-rods may be operated together, and I have withdrawn from said application andclaimed in the present application the features relating to the driving mechanism, retaining in said prior application the features relating to the swiveling device.

I have illustrated my invention in the accompanying drawings, in which Figure l is a view of the driving mechanism in elevation. Fig. 2 is a sectional view on line 2 2, Fig. 1. Fig. 3 is a view of the rotating cams or eccentrics. Fig. 4 is a sectional view on line 4 4, Fig. 3, showing the annuli in position.

Like letters refer to like parts in the several figures.

The wheel'snaft a is journaled within the sleeve a, supported upon the barrel 0. which constitutes the turn-table which is adapted to rotate about the barrel a, supported upon the upper end of a windmill-tower of any usual construction, and extending laterally from the sleeve a are the arms a a in which a shaft or axle a is journaled. Upon the wheel-shaft a a plurality of cams or eccen- .l lo model.)

tries are mounted. In the present case three such eccentrics are provided-to wit, 1) b 19 The eccentrics are placed at one hundred and twenty degrees apart, as shown in Fig. 3, and each of the eccentrics is surrounded by a ring, which is hollow and which is provided at the inner periphery with one or more oilholes or with a circular channel, which permits the oil to pass from the interior of the annulus or ring to the bearing-sleeves of the eccentrics. The cams b b b are encircled, respectively, by the rings or annulib b b As shown more clearly in Fig. 4, an oil-hole is provided through the wall of the eccentric communicating with the channel around the inner periphery of the hollow annuli, where by oil may be admitted. into the interior of the annuli and fed thence to the eccentric as the annuli travel back and forth. Upon the shaft or axle a are journaled the frames or casings c c 0 each having an upper wall 0 and a lower wall 0 against which the annulus corresponding thereto is adapted to roll. To the ends of the casings c c c the upper portions 61 d d 'of the pump-rods are respectively journaled. As the wind-wheel shaft rotates the cams moving within their respective annuli cause the annuli to roll back and forth, the annulus first rolling against the upper wall 0 of the frame to raise the same and then rolling against the lower wall 0 to lower the same. In this manner the rotation of the eccentric causes the annulus to roll successively in contact with the walls of the frame or casing, thereby reciprocating the same and imparting a reciprocating movement to the pump-rod.- The upper portions d d d of the pump-rods extend downward to a point below the barrel of the turn-table, where the swiveling devices are arranged. The swiveling device may take the form shown in my application above mentioned or may be constructed in any other desired manner, and as the swiveling device forms no part of the present invention I have omitted the same from the drawings.

While I have illustrated my invention in connection with three cams, the drawings sufficiently illustrate the manner in which one, two, or a greater number of cams and inclosing annuli may be employed with the corresponding number of frames or casings to actuate one, two, or a greater number of pumprods.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, a plurality of eccentrics, an annulus surrounding each, a reciprocating frame or casing for each annulus upon the wall of which the annulus is adapted to roll, and rods or parts connected to and reciprocated by the respective frames, substantially as described.

2. In combination, three eccentrics arranged at equal distance apart, an annulus surrounding each, a reciprocating frame or casing for each annulus upon the walls of which the annulus is adapted to roll, and rods or parts connected to and reciprocated by the respective frames, substantially as descri bed.

3. In combination, the shaft of a windmill, an eccentric thereon, an annulus encircling said eccentric, a pump-rod, and a reciprocating part connected with the pump-rod and having a wall against which said annulus is adapted to roll, substantially as described.

4. In combinaiioman eccentric, an annulus encircling the same and a reciprocating part against which the annulus is adapted to roll, said annulus having an interior oil-chamber communicating with the periphery of said eccentric, substantially as described.

5. In combination, an eccentric, an annulus encircling the same and a part against which the annulus is adapted to roll, said annulus having an interior annular channel communicating with the peripheryof said eccentric, substantially as described.

6. In combination, an eccentric,au annulus encircling the same, and a part against which the annulus is adapted to roll, said annulus having an interior annular channel and a communicating passage between said channel and the periphery of the eccentric and extending completely around the inner periphery of the ann ulus,substantially as described.

7. In combination, an eccentric,an annulus encircling the same and having an annular oil-chamber opening at the inner periphery of the annulus, and an oil-hole passing through the eccentric and communicating with said oil-chamber, substantially as described.

In witness whereof I have hereunto subscribed my name in the presence of two witnesses.
